MHLA3029RBTS 产品概述
一、产品简介
MHLA3029RBTS 为 MEIHUA（美华）出品的双色指示灯器件，采用 SIP-3 插针式封装，外观为雾状白色透镜，发光颜色包含红色与蓝色两种。该器件设计用于面板指示、状态显示及一般信号提示场合，兼具良好的可视性与装配便捷性，适合自动化设备、消费电子及通讯设备等领域。
二、主要参数
- 发光颜色：红色、蓝色
- 波长（典型）：红 630–650 nm；蓝 465–474 nm
- 正向电压（Vf）：红 1.8–2.4 V；蓝 2.8–3.4 V
- 额定正向电流（If）：20 mA（典型工作点）
- 最大功率耗散：80 mW
- 发光强度（Iv）：60 mcd（稳态低亮度） / 1000 mcd（高亮度型号或最大发光条件）
- 发光角度：60°
- 工作温度：-40 ℃ ～ +85 ℃
- 封装形式：SIP-3（直插/插针式）
三、性能特点
- 双颜色输出，便于状态区分（红/蓝）；雾状透镜使光分布更均匀，减少眩光。
- 低功耗设计，20 mA 工作电流下红、蓝两色均在安全功率范围内（P = Vf × If ≤ 80 mW）。
- 60° 发光角度适合面板指示与近距离可视观察。
- 宽工作温度范围，满足工业级环境可靠性要求。
四、典型使用建议
- 限流电阻计算示例（电源 5 V）：红色 Vf ≈ 2.1 V → R ≈ (5 − 2.1) / 0.02 ≈ 145 Ω（可选 150 Ω）；蓝色 Vf ≈ 3.1 V → R ≈ (5 − 3.1) / 0.02 ≈ 95 Ω（可选 100 Ω）。
- 注意功率余量：在 20 mA 下，红色功耗约 42 mW，蓝色约 62 mW，均低于 80 mW 上限；若需更高亮度或并联驱动，请评估热管理与老化影响。
- 若用于脉冲驱动，可短时提高电流以提升峰值亮度，但需控制占空比并确保平均功率不超过器件额定值。
五、封装与装配注意
- SIP-3 直插式封装，便于手工焊接与自动插件；具体引脚定义与机械尺寸请参考完整数据手册。
- 建议回流/手工焊接温度与时长按通用 LED 工艺控制（避免长时间高温），焊接后建议进行外观与功能检查。
- 防静电保护：LED 对 ESD 敏感，装配与搬运中请采取相应防护措施（接地、导电腕带等）。
六、可靠性与环境
- 工作温度范围 -40 ～ +85 ℃，适用于大多数室内及工业环境。
- 建议存储环境避免高湿与强氧化性气体，长时间储存前保持防潮包装。
- 在实际应用中应考虑热循环、振动及长期电流带来的光衰与色坐标漂移，必要时进行寿命测试与验证。
总结：MHLA3029RBTS 提供稳定的红/蓝双色指示功能，SIP-3 封装利于集成与装配，适合需要清晰状态提示的电子产品。选择与使用时，请结合电源、电流限制与散热条件，并参照厂方完整数据表以获取精确的机械与电气特性。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
